A resident of a long-term care facility receives 12.5 mg metoprolol (Lopressor) at 8 AM and 8 PM daily. Before administering this drug, the nurse should perform and document what assessment findings?
Temperature and respiratory rate
Heart rate and blood pressure
Level of consciousness and pain level
Oxygen saturation and respiratory rate
The Correct Answer is B
A) Temperature and respiratory rate:
While monitoring temperature and respiratory rate are important aspects of a comprehensive assessment, they are not the priority assessments before administering metoprolol. Metoprolol is a beta-blocker primarily used to lower heart rate and blood pressure, so assessing the client's heart rate and blood pressure is more relevant.
B) Heart rate and blood pressure:
This is the correct answer. Before administering metoprolol, it is essential to assess the client's heart rate and blood pressure. Metoprolol is a beta-blocker medication that primarily affects heart rate and blood pressure. Monitoring these vital signs helps ensure that the medication is administered safely and effectively.
C) Level of consciousness and pain level:
Assessing the client's level of consciousness and pain level are important aspects of nursing care, but they are not the priority assessments before administering metoprolol. These assessments may be relevant depending on the client's overall condition and specific care needs, but they are not directly related to the action or side effects of metoprolol.
D) Oxygen saturation and respiratory rate:
Monitoring oxygen saturation and respiratory rate are important aspects of respiratory assessment, but they are not the priority assessments before administering metoprolol. While metoprolol can affect respiratory function as a potential side effect, its primary action is on heart rate and blood pressure. Therefore, assessing heart rate and blood pressure are more pertinent before administering this medication.

Correct Answer is B
Explanation
B) Tachycardia:
Anticholinergic drugs, by blocking the action of acetylcholine at muscarinic receptors, can lead to increased sympathetic activity, resulting in tachycardia. Acetylcholine normally acts to moderate heart rate via vagal stimulation, so blocking its effects with anticholinergic medications can lead to an unopposed sympathetic response, causing an increase in heart rate.
A) Urinary Frequency:
Anticholinergic drugs typically cause urinary retention rather than urinary frequency. By blocking muscarinic receptors in the bladder, these medications can lead to decreased bladder contractility and urinary retention. Urinary frequency is not a common adverse effect of anticholinergic drugs.
C) Tachypnea:
Tachypnea, or rapid breathing, is not a typical adverse effect of anticholinergic medications. While anticholinergic drugs can affect respiratory secretions and cause drying of mucous membranes, leading to potential respiratory issues, tachypnea specifically is not commonly associated with their use.
D) Hypotension:
Anticholinergic drugs are more likely to cause hypertension rather than hypotension. By blocking the parasympathetic nervous system, these medications can lead to sympathetic dominance, resulting in increased blood pressure. Hypotension is not a typical adverse effect of anticholinergic drugs.
Correct Answer is ["B","C","E"]
Explanation
A) Is it caused by demyelination of the nerve fibers:
Myasthenia gravis is not primarily caused by demyelination of nerve fibers. It is characterized by dysfunction at the neuromuscular junction, specifically involving the acetylcholine receptors.
B) Is it thought to be an autoimmune disease:
This is correct. Myasthenia gravis is considered an autoimmune disorder in which the body's immune system mistakenly targets and attacks its own tissues, particularly the acetylcholine receptors at the neuromuscular junction.
C) It is associated with destruction of acetylcholine receptor sites:
This is correct. In myasthenia gravis, there is a reduction in the number of functional acetylcholine receptors due to autoimmune-mediated destruction or blocking of these receptors.
D) Once symptoms present, it has a 5-year survival rate:
This statement is inaccurate. Myasthenia gravis is a chronic condition, but survival rates are not determined by the onset of symptoms. With appropriate treatment, many individuals with myasthenia gravis can manage their symptoms effectively and have a normal life expectancy.
E) It is a chronic and progressive muscular disease:
This is correct. Myasthenia gravis is a chronic neuromuscular disorder characterized by fluctuating muscle weakness and fatigue. While it is chronic, it is not necessarily progressive in all cases, as symptoms may stabilize or improve with treatment.
F) Is it best treated with antibiotics:
Antibiotics are not the primary treatment for myasthenia gravis. Treatment typically involves medications that enhance neuromuscular transmission, such as acetylcholinesterase inhibitors or immunosuppressive drugs, along with other supportive measures.
